Qualifying 2025 installations may fall within the federal Section 25C Energy Efficient Home Improvement Credit period. Property placed in service after December 31, 2025 does not. Do not promise a current federal credit for a 2026 installation.
If you placed qualifying property in service in 2025, you may still have a 2025 return to file. For that property, the taxpayer must report its QMID. Direct tax questions to a tax professional.
Climate Pros SD is a referral service. We match San Diego County homeowners with licensed HVAC professionals. We do not prepare tax returns.
This isn’t tax advice. Confirm current IRS language at irs.gov. State and utility programs are separate and have their own 2026 status.

How 25C works for a qualifying 2025 placed-in-service date
The credit is a tax credit, not a utility rebate. It reduces federal income tax owed. It is nonrefundable.
The IRS annual limit for qualified heat pumps and heat pump water heaters was $2,000. Do not treat that as a check in the mail, and do not apply it to a 2026 placed-in-service date.
Placed in service is the date that matters, not the contract date. Equipment bought in 2025 and installed in 2026 is a 2026 placed-in-service fact. No 25C.
What “qualified” means on this page
We will not invent ENERGY STAR “Most Efficient” lists or 16 SEER2 thresholds here. The IRS page is the source. The contractor’s invoice and manufacturer spec sheet are the documents your tax professional uses. The QMID must be reported for qualifying 2025 property.
What’s included in qualified expenses
Ask your tax professional what the IRS currently treats as qualified 25C expenses for a 2025 placed-in-service date. Get itemized invoices (equipment, labor, permit) so the return has a paper trail. This brand does not define qualified expenses for you.
What’s left for 2026 installs
With 25C gone for 2026 placed-in-service dates, the federal piece is off the table for systems installed this year.
State and utility programs are not a substitute 25C:
- TECH Clean California single-family heat pump HVAC and heat pump water heater incentives were fully reserved and stopped accepting new reservations on November 14, 2025.
- HEEHRA single-family rebates were fully reserved statewide as of February 24, 2026. No new single-family income-verification applications were being accepted. Existing approved reservations may continue. A submitted request is not approved funding.
- As of July 15, 2025, a project cannot receive both a TECH incentive and a HEEHRA rebate.
- SDG&E Golden State Rebates Program retail rebate offerings have ended. Confirm any other SDG&E program separately.
See 2026 heat pump rebate stack and SDG&E eligibility.
How to claim a qualifying 2025 install
- Keep the itemized invoice, model numbers, placed-in-service date, and QMID information.
- Work with a tax professional on the 2025 federal return. They will use current IRS forms and instructions.
- Remember the credit is nonrefundable. If you did not owe enough federal tax, unused 25C does not become a refund on this page’s reading of the IRS claim.
Climate Pros SD does not file Form 5695.
Common 25C mistakes
- Treating a 2026 install as if 25C still applied
- Using the contract date instead of the placed-in-service date
- Skipping QMID on a qualifying 2025 claim
- Treating the $2,000 heat-pump limit as a rebate check
- Assuming the matched HVAC company files the tax credit (they don’t)
Heat pump water heaters
The IRS annual limit language covers qualified heat pumps and heat pump water heaters at $2,000. How that interacts with a household that did both in 2025 is a tax-professional question. For a 2026 placed-in-service date, 25C does not apply to either.
FAQs
Is the 25C tax credit available in 2026?
Not for property placed in service after December 31, 2025. If you installed in 2025, that is a 2025 return question, including QMID.
How much was the federal HVAC tax credit?
The IRS says the annual limit for qualified heat pumps and heat pump water heaters was $2,000. The credit is nonrefundable. This site will not add other category dollar caps.
What HVAC systems qualified for the 25C tax credit?
Follow the IRS equipment rules for the year the property was placed in service. Do not use this page as the spec sheet.
Can I claim both the federal tax credit and SDG&E rebates?
For a qualifying 2025 install, federal tax credits and utility rebates are different systems. For a 2026 install there is no 25C. SDG&E Golden State retail offerings have ended. Confirm anything else currently funded.
How do I claim the 25C tax credit for a 2025 install?
Through your 2025 federal return, with QMID, using a tax professional. Keep invoices.
Is the 25C credit refundable?
No. Nonrefundable.
What if I didn’t owe federal taxes in 2025?
Nonrefundable credits only offset tax liability. A tax professional can tell you what that meant on your return.
Does my contractor handle the 25C paperwork?
No. The contractor provides invoices and specs. You and your tax professional file. There is no 25C filing for a 2026 placed-in-service date.
How long was the 25C credit available?
This site states the placed-in-service cutoff: after December 31, 2025, property does not qualify. Legislative history beyond that belongs on IRS pages, not in extra slogans here.
